MACHINE FOR USE IN THE MANUFACTURE OF BOOTS AND SHOES.

Specification of Letters Patent.

Patented Dec. 31, 1912.

Application filed February 14, 1911. Serial No. 608,500.

To all whom it may concern Be it known that I, FRANK FLEURY, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain Im provements in Machines for Use in the Manufacture of Boots and Shoes, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to machines for shaping or molding the uppers of boots or shoes and is herein shown as embodied in a machine for molding the heel end of a stitch down shoe upper and forming thereon an outturned flange.

An object of the invention is to provide simple and compact means for molding the heel end of a stitch down shoe upper and forming thereon an outturned flange in one continuous operation, whereby the preparation of the upper for the attachment of the sole may be effected quickly and with comparatively unskilled labor. Other objects and features of the invention will be apparent when the following description and claims are considered in connection with the accompanying drawings, in which- Figure 1 is a side elevation of a machine embodying the invention; Fig. 2 is a detail perspective showing the molds in operative relation to each other; Fig. 3 is a vertical section through the molds showing the po' sition of the operative parts of the machine at the end of the molding operation.

The molding means proper comprises a female mold 2 and a male mold 4, the female mold being carried upon a plate (3 attached to the base of the frame 8 in such manner that it can readily be replaced by a mold of a different size. The male mold 4 is connected to a plate 10 by screws 12 threaded into said mold and having heads 14 resting normally in counter-bored seats 16 in said plate. The plate 10 is provided with a stem 18 held by a set screw 20 in a slide 22 arranged in guideways 24 and 26 in an overhanging part of the frame 8.

The slide 22 is moved vertically by means of a treadle lever 28 pivoted at 29 in upstanding ears 30 of the frame 8, said lever having a rounded end 31 which enters an opening 32 in the slide 22. The treadle lever 28 is so shaped that its weight normally maintains the slide 22 in its uppermost position. A foot piece 34 at the lower end of said treadle lever may be engaged by the foot of the operator when it is desired to depress the slide 22 to bring the male mold 4 into coooperative relation with the female mold 2.

WVhen the molds are in cooperative relation to each other the forward edge of the male mold 4 projects over the edge of the female mold a slight distance, the amount of the projection being substantially equal to the thickness of the material interposed between the molds. This permits the operation of a flange former which is mounted upon the male mold, said flange former being expansible and comprising plates 36 and 38 confined upon the male mold 4 for sliding movement by screws 40 and 42 passing through inclined guiding slots 44 and 46, re spectively, in said plates. The plates 36 and 38 are normally maintained in engagement with each other by springs 48 and 50 connected at their respective ends to studs or screws in the respective plates.

The movements of the plates toward and away from each other are guided both by the slots 44 and 46 and by upper and lower slots 52 and 54 into which project upper and lower studs 56 and 58 upon the male mold. l/Vhen the plates 36 and 38 are in engagement with each other their outer edges lie substantially flush with the outer edge of the male mold. The vertical extent of the plates 36 and 38 is, however, somewhat greater than the vertical extent of the male mold 4, so that the plates project above the upper edge of the male mold and are preferably normally in engagement with the plate 10. The plate 10 is therefore normally spaced from the male mold 4' a distance cor responding to the amount of projection of the lates 36 and 38 above the male mold, and 1s yieldingly kept in this spaced relation by springs 60 surrounding the screws 12, the action of the springs being aided by gravity. The slots 44, 46 and 52, 54 are so inclined to the longitudinal axis of the shoe that the operative movement of the flange former will be toward the side as well as toward the rear end of the shoe.

The operation of the machine is as fol lows: The parts being in the position shown in Fig. 1, a shoe upper is placed in the female mold 2 with its toe end placed behind the heel mold, providing the toe end of the upper is connected to the heel end. In placing the upper in the female mold the operator will cause the upper to project beyond the front face of the female mold a distance equal to the desired width of the flange to be formed on said upper. The operator then depresses the slide 22 to bring the male mold 4 into contact with the stock in the female mold. When the movement of the male mold is interrupted the continued depression of the slide 22 will cause the plate 10 to compress the springs 60 and to move the plates 36 and 38 downward. As above pointed out, the movements of the plates 36 and 38 will not be directly downward but will be partly to the side, owing to the action of the screws 40 and 42 and the studs .56 and 58 in the inclined slots in said plates. The plates 36 and 38 will thus be caused to engage the projecting margin of the upper and to turn it out over the edge of the female mold. When the molding and flange forming operation has been completed, the operator releases the treadle le ver 28 and the weight of this lever moves the slide 22 to its uppermost position and permits the springs 60, 48 and 50 to restore the parts to the relative positions shown in Fig. 1. To guide the male mold 4 in its movements toward andrfrom the plate 10 a pin 62, depending from the stem 18, enters an opening 64 in said male mold.

Having now described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:
